研制了一种新型掺铒碲酸盐玻璃TeO2-ZnO-Na2O-Bi2O3，利用Judd-Ofelt和McCumber理论计算了Er3+离子的强度参数、自发辐射几率、吸收截面和发射截面等光谱参数。

This method is independent from flow data, having fast rendering rate and high contrast output image. The parameters have obvious physical meaning, and different vision effect visualization output results are derived from different parameters combination. This method can take full advantage of the graphic card accelerator, and has successful application in the dynamic visualization of the flow data in crystal growth experiment during task research work.

No, AQL is short for Acceptable Quality Level,not Average Quality Level .

的确是指参数，不过达到了这个参数，也就符合了客户的标准。所以又通常称为质量标准。

Because the thermal properties of materials are time-depandent,it's possible to increase the accurateness of numerical simulation with the variable thermal properties.

由于材料的物性参数是随着温度时刻变化，采用变物性参数可进一步缩小模拟结果与实际间的差异。

It introduces the development of a pocket bio-chemical blood measurement apparatus,which can test such parameters as blood sugar, lactic acid, cholesterol, acetone body ,and make the diagnosis for every testing results.

介绍了一种便携式全血多参数生化检测仪器的研制。能对血糖、乳酸、胆固醇、酮体四项参数进行测试并做出实时诊断。

At the same time, we introduce a unified chaotic system with single parameter,called Lorenz system families, which contains the Lorenz and the Chen systems as two dualsystems at the two extremes of its parameter spectrum, and acritical system as a transitionsystem.

同时，提出了一个单参数的统一混沌系统--Lorenz系统族，它包含Lorenz系统和Chen系统作为参数区间的两个极端系统，临界系统作为一个过渡系统。

This will be achieved by passing a parameter to the index action that will tell what list the user wants to see.

我们是通过想index操作传输一个参数来实现，这个参数会告诉index操作用户想要查看什么样的清单。

If you define a greedy macro, you are effectively telling NASM how it should expand the macro given any number of parameters from the actual number specified up to infinity; in this case, for example, NASM now knows what to do when it sees a call to writefile with 2, 3, 4 or more parameters.

如果你定义了一个贪婪宏，你也就告诉了NASM如何扩展这个宏，无论参数个数多大。本例中当NASM看到用2，3，4等多个参数调用writefile时知道如何去扩展它。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
